Method of making an injection molded product packaging having a humidity control material

Abstract

The present disclosure, in one embodiment, relates to an injection molded container for holding a product, wherein the container is configured to house a humidity control product that may regulate the relative humidity of the inner body of the container such that the product housed therein may be kept at an optimal humidity.

What is claimed is: 
     
       1. A method of making an injection molded container for holding a product, the method comprising:
 forming an injection mold that has two wall portions, including an inner wall and an outer wall, whereby a cavity is formed between the inner wall portion and the outer wall portion, the cavity having a cavity opening; 
 injecting a molten material that in a set phase will be liquid impermeable and substantially vapor impermeable into the outer wall portion of the mold; 
 injecting a molten material that in a set phase will be liquid impermeable and vapor permeable into the inner wall portion of the mold; and 
 inserting into the cavity opening a humidity control product. 
 
     
     
       2. The method of making an injection molded container for holding a product of  claim 1 , further comprising sealing the cavity opening after the cavity has been filled with the humidity control product. 
     
     
       3. The method of making an injection molded container for holding a product of  claim 2 , wherein the humidity control product is a one-way humidity control product. 
     
     
       4. The method of making an injection molded container for holding a product of  claim 3 , wherein the humidity control product is liquid water. 
     
     
       5. The method of making an injection molded container for holding a product of  claim 2 , wherein the humidity control product is a desiccant. 
     
     
       6. The method of making an injection molded container for holding a product of  claim 1 , wherein the humidity control product is a two-way humidity control product. 
     
     
       7. The method of making an injection molded container for holding a product of  claim 6 , wherein the humidity control product is a loose, free-flowing humidity control product. 
     
     
       8. The method of making an injection molded container for holding a product of  claim 7 , further comprising sealing the cavity opening after the cavity has been filled with the humidity control product. 
     
     
       9. The method of making an injection molded container for holding a product of  claim 6 , wherein the humidity control product is a self-contained humidity control product. 
     
     
       10. The method of making an injection molded container for holding a product of  claim 9 , wherein the humidity control product is optimized to set the RH range of an inner body of the container to about 62%. 
     
     
       11. The method of making an injection molded container for holding a product of  claim 6 , wherein the humidity control product is optimized to set the RH range of an inner body of the container to about 62%. 
     
     
       12. The method of making an injection molded container for holding a product of  claim 6 , wherein the humidity control product is optimized to set the RH range of an inner body of the container to between about 50% and 80%.
